The latest companies to join the user list of the TruPunch 1000 entry-level CNC punching machine from Luton-based Trumpf Ltd (
www.uk.trumpf.com) are Wiltshire-based Sunflow Ltd (a specialist in the manufacture of bespoke, low input electric heaters) and Glasgow-based NCE Switchgear (a provider of motor control, instrumentation and distribution electrical solutions).
Sunflow, a first-time Trumpf customer, is the only British manufacturer of refractory clay heaters. Formed in April 2010, the company now employs 40 people and has an annual turnover of around £3 million.
The move to install a Tru-Punch 1000 (pictured) has saved the cost of sub-contracted parts and introduced greater control over quality and production.
While there are many reasons for Sunflow’s success, one of the biggest factors is the quality it offers. In fact, the company is so confident in its products that the heaters come with a 10-year guarantee.
Managing director Suzanne Pesics said: “Until last year, we were outsourcing punched sheet metal parts for our radiators. However, the quality wasn’t up to our high standards. We knew that bringing punching in-house would both address this issue and introduce greater control over our production schedule.”
NCE Switchgear was already familiar with TruPunch 1000 technology and installed two of the entry-level TruPunch 1000 machines in July 2014.
In addition to punching electrical enclosures and related components, they also allow NCE Switchgear to form threads, make extrusions and bend flanges for complete processing in a single clamping.
Generally, these two machines are working with 2mm-thick Zintec, although some parts are also made from 2.5mm galvanised steel.
